Pressureless sintering of boron carbide - ScienceDirect

Jan 01, 2006· Boron carbide powder used for this study was prepared by carbothermic reduction of boric acid in an Acheson furnace. Chunklets of boron carbide were crushed in a jaw crusher and ground in a hammer mill to obtain particles of less than 45 μm.Fine powders of approximately 1 μm size used in these sintering studies were prepared by micronising these coarse powders in a planetary mill.

"Grinding with electroplated cubic boron nitride (CBN ...

Electroplated cubic boron nitride (CBN) wheels are manufactured with a single layer of CBN superabrasive grains held on the wheel hub by an electroplated nickel bond. Unlike other conventional and superabrasive wheels, these wheels are not periodically trued or dressed. Consequently, their performance during grinding varies significantly as the wheel wears down and its topography changes.
